A vaccine is a biological preparation made to immunize the body to prevent causing disease. Even if the host develops antibodies, the human immune system is not perfect and in any case the immune system might still not be able to defeat the infection immediately. In this case, the infection will be less severe and heal faster. There are several types of vaccines in use. These represent different strategies used to try to reduce risk of illness, while retaining the ability to induce a beneficial immune response. Different types of vaccines are: Killed, Attenuated , Toxoid; Subunit ;Conjugate ;Valence and Heterotypic. The immune system recognizes vaccine agents as foreign, destroys them, and ""remembers"" them. When the virulent version of an agent is encountered, the body recognizes the protein coat on the virus, and thus is prepared to respond, by neutralizing the target agent before it can enter cells, and recognizing and destroying infected cells before that agent can multiply to vast numbers.
